Hello,
I am trying to access the Apple Music Feed API, but I am recieving a 401 Unauthorized error message whenever I try to access it.
I have tried using my own code to generate a JWT and directly call the API (which can call the standard Apple Music API successfully).

> Host: api.media.apple.com

Does this API need to be enabled on my account separately from the main Apple Music API? The documentation reads to me as if anyone with an Apple Developer Programme membership can use this API and I did not see any information regarding any other requirements

Hi all,
i can successfully match music using shazamkit on Apple using SwiftUI, a simple app that let user to load an audio file and exctracts the relative match, while i am unable to match music using shamzamkit on Android. I am trying to make the same simple app but i cannot match music as i get MATCH_ATTEMPT_FAILED every time i try to. I don't know what i am doing wrong but the shazam part in the kotlin Android code is in this method :
suspend fun processAudioFileInBackground(
filePath: String,
developerTokenProvider: DeveloperTokenProvider
) = withContext(Dispatchers.IO) {
val bufferSize = 1024 * 1024
val audioFile = FileInputStream(filePath)
val byteBuffer = ByteBuffer.allocate(bufferSize)
byteBuffer.order(ByteOrder.LITTLE_ENDIAN)
var bytesRead: Int
while (audioFile.read(byteBuffer.array()).also { bytesRead = it } != -1) {
val signatureGenerator = (ShazamKit.createSignatureGenerator(AudioSampleRateInHz.SAMPLE_RATE_44100) as ShazamKitResult.Success).data
signatureGenerator.append(byteBuffer.array(), bytesRead, System.currentTimeMillis())
val signature = signatureGenerator.generateSignature()
println("Signature: ${signature.durationInMs}")
val catalog = ShazamKit.createShazamCatalog(developerTokenProvider, Locale.ENGLISH)
val session = (ShazamKit.createSession(catalog) as ShazamKitResult.Success).data
val matchResult = session.match(signature)
println("MatchResult : $matchResult")
setMatchResult(matchResult)
byteBuffer.clear()
}
audioFile.close()
}
I noticed that changing Locale in catalog creation results in different result as i get NoMatch without exception. Can you please help me with this?

t has been quite some time since I requested the Apple FPS package, yet I haven’t received it. I haven’t received any email either. Is there a developer support inquiry center where I can check the status of the process? Alternatively, could you share approximately how long it took for you to receive a response email?

Hello Apple Developer Community,
We are developing a music management platform for restaurants and cafes in Saudi Arabia. Our app enables businesses to schedule playlists and allows visitors to request songs via barcodes. Music playback is powered by Apple Music, and users must have their own Apple Music subscriptions to access the music. Our service charges a monthly subscription fee for these management features, not for music access itself.
Project Overview and MusicKit Role
Our app integrates MusicKit to leverage Apple Music’s catalog and playback capabilities. Users log in with their Apple Music accounts, ensuring they have an active subscription for music playback. Our platform’s value lies in its tools—playlist scheduling and song requests—which are built on top of MusicKit’s APIs. We offer these features exclusively in Saudi Arabia.
Legal Context in Saudi Arabia
In Saudi Arabia, to our understanding, no special licenses are required for playing music in commercial venues like restaurants and cafes. This means our clients can use Apple Music subscriptions for playback without additional performance rights licenses. While this aligns with local laws, we recognize that Apple’s global policies may impose stricter requirements, prompting our need for clarification.
Subscription Model and Monetization Concerns
We charge a monthly subscription fee for access to our app’s features (e.g., scheduling playlists and managing song requests). This fee is separate from the Apple Music subscription, which users must maintain for playback. However, Apple’s MusicKit terms state: "You agree not to require payment for or indirectly monetize access to the Apple Music service." We’re concerned whether our subscription model might be interpreted as indirectly monetizing Apple Music access, given its reliance on MusicKit for functionality.
Scheduling Feature and Synchronization Rights
Our app allows businesses to schedule playlists for general time slots (e.g., “play this playlist from 6 PM to 8 PM”). It does not support precise scheduling, such as playing a specific song at an exact moment (e.g., “play this song at 7:30 PM”). Apple’s guidelines mention that “deeper or more complex music integration” may require additional licenses, like synchronization rights. We’re unsure if our general scheduling feature crosses this threshold or remains within MusicKit’s standard usage.
Questions for Clarification
We’d greatly appreciate expert input on the following:
Monetization: Does our subscription fee for management features (scheduling and song requests) violate Apple’s policy against indirectly monetizing Apple Music access?
Local Context: Given that Saudi Arabia requires no additional licenses for commercial music playback, does this impact our compliance with Apple’s global terms?
Scheduling: Does our playlist scheduling for general time slots (not exact moments) fall within MusicKit’s permitted scope, or does it require further licensing?
Thank you in advance for any insights or guidance to ensure our app aligns with Apple’s policies!

Hi,
I've had a new deck installed in my car for about 1.5 weeks.
I'm having compatibility issues with my 15PM.
It happens both wired and wirelessly, I get the error "Accessory not supported by this device". It used to happen all the time, now it's 50/50. Sometimes it works.
I've removed and added Bluetooth multiple times on phone and deck, I bought a belkin usb-c to usb-a cable today and it seems to fix it but the problem comes back.
I've changed the setting "FaceID and passcode-allow access when locked-accessories."
The car stereo guy reckons it's definitely an issue with the phone not the deck, I'm inclined to believe him since the error states "by this device".
Any advice appreciated.

I am working on an app which plays audio - https://youtu.be/VbAfUk_eYl0?si=nJg5ayy2faWE78-g - and one of the features is, on restart, if you had paused playback of a file at the time the app was previously shut down (or were playing one at the time of shutdown), the paused state and position in the file is restored exactly as it was, on restart.
The functionality works. However, it seems impossible to get the "now playing" information in iOS into the right state to reflect that via the MediaPlayer API. On restart, handlers are attached to the play/pause/togglePlayPause actions on MPRemoteCommandCenter.shared(), and the map of media info is updated on MPNowPlayingInfoCenter.default().nowPlayingInfo.
What happens is that iOS's media view shows the audio as playing and offers a pause button - even though the play action is enabled and the pause action is disabled.
Once playback has been initiated (my workaround is to have the pause action toggle the play state, since otherwise you wouldn't be able to initiate playback from controls in a car without initiating it once from a device first).
I've created a simplified white-noise-player demo to illustrate the problem - simply build and deploy it, and then start the app, lock your device and look at the playback controls on the lock screen. It will show a pause button - same behavior I've described.
https://github.com/timboudreau/ios-play-pause-demo
I've tried a few things to narrow down the source of the issue - for example, thinking that not MPNowPlayingInfoPropertyPlaybackProgress and MPMediaItemPropertyPlaybackDuration might be the culprit (since the system interpolates elapsed time and it's recommended to update those properties infrequently) on startup might do the trick, but the result is the same, just without a duration or progress shown.
What governs this behavior, and is there some way to explicitly tell the media player API your current state is paused?
In Final Cut Pro, keyframes for transform parameters (such as Position, Scale, and Rotation) are automatically set to “Smooth” interpolation. This often results in undesired easing between keyframes, especially when linear motion is required.
Currently, we have to manually adjust each keyframe to "Linear" using the Video Animation Editor, which can be time-consuming when working with many keyframes.
Would it be possible to add an option to set the default keyframe interpolation to "Linear"—either globally in Preferences or per parameter in the Inspector?
This would greatly streamline the animation workflow for many editors.
Thank you for considering this request!
Are serialized parameters already available inside -pluginInstanceAddedToDocument via FxParameterRetrievalAPI or are they being read later?
In iOS 26 When we download any DRM content first time it is downloading again when we edit audios and Video Quality and start downloading it is freezing complete app. Neither it is crashing not giving any error.
Environment→ ・Device: iPad 10th generation ・OS:**iOS18.3.2
We're using AVAudioPlayer to play a sound when a button is tapped. In our use case, this button can be tapped very frequently — roughly every 0.1 to 0.2 seconds. Each tap triggers the following function:
var audioPlayer: AVAudioPlayer?
func soundPlay(resource: String, type: String){
guard let path = Bundle.main.path(forResource: resource, ofType: type) else {
return
}
do {
audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: path))
audioPlayer!.delegate = self
try audioSession.setCategory(.playback)
} catch {
return
}
self.audioPlayer!.play()
}
The issue is that under high-frequency tapping (especially around 0.1–0.15s intervals), the app occasionally crashes. The crash does not occur every time, but it happens randomly — sometimes within 30 seconds, within 1 minute, or even 3 minutes of continuous tapping.
Interestingly, adding a delay of 0.2 seconds between button taps seems to prevent the crash entirely. Delays shorter than 0.2 seconds (e.g.,0.15s,0.18s) still result in occasional crashes.
My questions are:
**Is this expected behavior from AVAudioPlayer or AVAudioSession?
Could this be a known issue or a limitation in AVFoundation?
Is there any documentation or guidance on handling frequent sound playback safely?**
Any insights or recommendations on how to handle rapid, repeated audio playback more reliably would be appreciated.
Hi!
I am writing a browser extension that allows you to control the playback of media content on a music service website. Unfortunately Safari does not support tracking changes to the audible property in an event tabs.onUpdated. Is there an alternative to this event? I'm looking for a way to track when the automatic inference engine interrupts playback on a music service website.
That you.

I’m developing a macOS audio monitoring app using AVAudioEngine, and I’ve run into a critical issue on macOS 26 beta where AVFoundation fails to detect any input devices, and AVAudioEngine.start() throws the familiar error 10877.
FB#: FB19024508
Strange Behavior:
AVAudioEngine.inputNode shows no channels or input format on bus 0.
AVAudioEngine.start() fails with -10877 (AudioUnit connection error).
AVCaptureDevice.DiscoverySession returns zero audio devices.
Microphone permission is granted (authorized), and the app is properly signed and sandboxed with com.apple.security.device.audio-input.
However, CoreAudio HAL does detect all input/output devices:
Using AudioObjectGetPropertyDataSize and AudioObjectGetPropertyData with kAudioHardwarePropertyDevices, I can enumerate 14+ devices, including AirPods, USB DACs, and BlackHole.
This suggests the lower-level audio stack is functional.
I have tried:
Resetting CoreAudio with sudo killall coreaudiod
Rebuilding and re-signing the app
Clearing TCC with tccutil reset Microphone
Running on Apple Silicon and testing Rosetta/native detection via sysctl.proc_translated
Using a fallback mechanism that logs device info from HAL and rotates logs for submission via Feedback Assistant
I have submitted logs and a reproducible test case via Feedback Assitant : FB#: FB19024508]
I've got a setup using AVAudioEngine with several tone generator nodes, each with a chain of processing nodes, the chains then mixed into the main output.
Generator ➡️ Effect ➡️... ➡️ .mainMixerNode ➡️ .outputNode).
Generator ➡️ Effect ➡️... ⤴️
...
Generator ➡️ Effect ➡️... ⤴️
The user should be able to mute any chain individually. I've found several potential approaches to muting, but not terribly happy with any of them.
Adjust the amplitudes directly in my tone generators. Issue: Consumes CPU even when completely muted. 4 generators adds ~15% cpu, even when all chains are muted.
Detach/attach chains that are muted/unmuted. Issue: Causes loud clicking/popping sounds whenever muted/unmuted.
Fade mixer output volume while detaching/attaching a chain (just cutting the volume immediately to 0 doesn't get rid of the clicking/popping). Issue: Causes all channels to fade during the transition, so not ideal.
The rest of these ideas are variations on making volume control+detatch/attach work for individual chains, since approach #3 worked well.
Add an AVAudioMixer to the end of each chain (just for volume control). Issue: Only the mixer on the final chain functions -- the others block all output. Not sure what's going on there.
Use matrix mixer (for multi-input volume control). Plus detach/attach to reduce CPU if necessary. Not yet attempted, due to perceived complexity and reports of fragility in order of wiring in. A bunch of effort before I even know if it's going to work.
Develop my own fader node to put on the end of each channel. Unlike the tone generator (simple AVSourceNode), developing an effect node seems complex and time consuming. Might not even fix CPU use.
I'm not completely averse to the learning curve of either 5 or 6, but would rather get some guidance on best approach before diving in. They both seem likely to take more effort than I'd like for the simple behavior I'm trying to achieve.
It's been well over a year since Apple added favoriting of artists back to Apple Music (the little star icon on an artist page), but yet I still haven't seen a way to get this data from an authenticated user from Music API. I was expecting to hear something about this during the WWDC, but there have been no announcements that I've caught.
Has anyone else heard anything? People assume when they provide access to their Apple Music account that we can actually get to the data in their Apple Music account, and we end up looking a little dumb not being able to get this core data.

I'm using AVAudioSession to record sound in my application. But I recently came to realize that when the app starts a recording session on a tablet, OS automatically sets the tablet volume to 50% and when after recording ends, it doesn't change back to the previous volume level before starting the recording. So I would like to know whether this is an OS default behavior or a bug?
If it's a default behavior, I much appreciate if I can get a link to the documentation.
Since iOS 18, the system setting “Allow Audio Playback” (enabled by default) allows third-party app audio to continue playing while the user is recording video with the Camera app. This has created a problem for the app I’m developing.
➡️ The problem:
My app plays continuous audio in both foreground and background states. If the user starts recording video using the iOS Camera app, the app’s audio — still playing in the background — gets captured in the video — obviously an unintended behavior.
Yes, the user could stop the app manually before starting the video recording, but that can’t be guaranteed. As a developer, I need a way to stop the app’s audio before the video recording begins.
So far, I haven’t found a reliable way to detect when video recording starts if ‘Allow Audio Playback’ is ON.
➡️ What I’ve tried:
— AVAudioSession.interruptionNotification → doesn’t fire
— devicesChangedEventStream → not triggered
I don’t want to request mic permission (app doesn’t use mic). also, disabling the app from playing audio in the background isn’t an option as it is a crucial part of the user experience
➡️ What I need:
A reliable, supported way to detect when the Camera app begins video recording, without requiring mic access — so I can stop audio and avoid unintentional overlap with the user’s recordings.
Any official guidance, workarounds, or AVFoundation techniques would be greatly appreciated.
Thanks.
When I play an m3u8 video using AVPlayer, it can play smoothly at 2x speed. However, when I set it to 3x speed, the playback is not smooth and there is no sound.

Hi Apple Music API / MusicKit / MediaPlayer Team,
Similar to the currentPlaybackRate keeps the same pitch, it would be great to have a currentPlaybackPitch parameter as well. Alternatively, adding a preservesPitch parameter would also work.
I see that iOS 26 AutoMix on Apple Music currently does pitch shifting during music transitions, so maybe this is something that could be exposed on the later betas of iOS 26?
Main feature request we get is to have simple pitch changes to Apple Music we play through our app. Is this being considered?
